The meter has a number of different possible system wiring configurations (see Wiring Diagrams, page 5). To configure the meter,
set the System Type via the User Interface or Modbus register 130 (if so equipped). The System Type tells the meter which of its
current and voltage inputs are valid, which are to be ignored, and if neutral is connected. Setting the correct System Type prevents
unwanted energy accumulation on unused inputs, selects the formula to calculate the Theoretical Maximum System Power,
and determines which phase loss algorithm is to be used. The phase loss algorithm is configured as a percent of the Line-to-Line
System Voltage (except when in System Type 10) and also calculates the expected Line to Neutral voltages for system types that
have Neutral (12 & 40).
Values that are not valid in a particular System Type will display as “----” on the User Interface or as QNAN in the Modbus registers.

•
•
•
•
S elect current interrupt capacity based on the installation category and fault current capability.
Select over-current protection with a time delay.
Select a voltage rating sufficient for the input voltage applied.
Provide overcurrent protection and disconnecting means to protect the wiring. For AC installations, use Veris AH02,
AH03, AH04, or equivalent. For DC installations, provide external circuit protection. Suggested: 0.5 A, time delay fuses.
• The earth connection (G) is required for electromagnetic compatibility (EMC) and is not a protective earth ground.

as the reference voltage for setting the Phase Loss threshold.
Maximum is 32000 Volts. For system type 1+N (10), this is a Line to
Neutral Voltage, indicated by “V LN”. Note: the meter will reject settings
that are not within the meter’s operating range when divided by the PT
ratio.
System Power:
MX KW – The theoretical Maximum System Power is calculated by the
meter from the System Voltage, CT size, and System Type. Power
Factor is assumed to be unity. The value of System Power is used to
determine which combinations of pulse weight and duration are valid
and will keep up with the maximum power the meter will see. This value
is read only.

solution, the meter will display the wrench, show “ConF” in the
ALARM -> PULSE screen, and enable Energy pulse output
configuration error bit in the Modbus Diagnostic Alert Bitmap (if
equipped).
Wh/P - Set Pulse Energy: In Watt Hours (& VAR Hours, if
present) per Pulse. When moving down to a smaller energy, the
meter will not allow the selection if it cannot find a pulse duration
that will allow the pulse output to keep up with Theoretical
Maximum System Power (see S_PWR screen). When moving
up to a larger energy, the meter will jump to the first value where
it can find a valid solution.
mS/P – Minimum Pulse Duration Time: This read only value
is set by the meter to the slowest duration (in mS per closure)
that will keep up with the Theoretical Maximum System Power.
The open time is greater than or equal to the closure time. The
maximum Pulses Per Second (PPS) is shown in yellow.

Overview
TM
The E50C1A Basic Data Set (BDS) features Wh and VARh accumulators. The meter supports variable CTs and PTs, allowing a much
wider range of operation from 90V x 5A up to 32000V x 5000A. To promote this, the meter permits variable scaling of the 16-bit
integer registers via the scale registers. The 32-bit floating point registers do not need to be scaled.
Integer registers begin at 001 (0x001). Floats at 257 (0x101). Configuration registers at 129 (0x081). Values not supported in a
particular System Type configuration will report QNAN (0x8000 in Integer Registers, 0x7FC00000 in Floating Point Registers).

82-32000
System Voltage: This voltage is line to line, except for system type 10 which is line to neutral. The meter uses
this value to calculate the full scale power for the analog outputs and pulse configuration (below), and as full
scale for phase loss (register 142). The meter will refuse voltages that are outside the range of 82-660 volts
when divided by the PT Ratio (above).

Theoretical Maximum System Power: This read-only value is the theoretical max. power the meter can expect to

recalculates this value if the user changes the CT size, system type, or system voltage. This integer value has
the same scale as other integer power registers (see register 140 for power scaling).

Description
Phase Loss Voltage Threshold in percent of system voltage (register
134). Default is 10 (%). Any phase (as configured in register 130)
that drops below this threshold triggers a Phase Loss alert - i.e.
if the System voltage is set to 480 V L-L, the L-N voltage for each
phase should be 277 V. When the threshold is set to 10%, if any
phase drops more than 10% below 277 V, (less than 249 V), or
if any L-L voltage drops more than 10% below 480 V (less than Phase Loss Output
432 V) the corresponding phase loss alarm bit in register 146 will
be true.
Note: The phases tested are determined by

register 130), both Line to Neutral and Line to Line voltages are
tested. In a 3-phase Δ System type (31 in register 130), only Line
to Line voltages are examined. In a single split-phase (2 + N)
system type (12 in register 130), just the line to neutral voltage
are compared.
